Early strength agent for improving strength and durability of concrete and preparation method thereof
The invention relates to the field of concrete materials, and particularly discloses an early strength agent for improving the strength and durability of concrete and a preparation method of the early strength agent. The invention discloses an early strength agent for improving the strength and durability of concrete. The early strength agent is prepared from the following raw materials in parts by weight: 20-30 parts of nano silicon dioxide, 10-20 parts of calcium bromide, 5-10 parts of silica fume, 2-4 parts of triethanolamine, 5-10 parts of ethylene glycol and 8-15 parts of an expanding agent. According to the early strength agent for improving the strength and durability of the concrete, corrosion and damage of chlorides and sulfates to concrete reinforcements are reduced, the nano-silica, the silica fume and the calcium bromide are mutually combined to synergistically improve the strength and durability of the concrete, meanwhile, invasion and corrosion of chloride ions are reduced, and the impermeability of the concrete is improved.
本申请涉及混凝土材料领域，具体公开了一种提高混凝土强度和耐久性的早强剂及其制备方法。一种提高混凝土强度和耐久性的早强剂，包括以下重量份原料：纳米二氧化硅20‑30份，溴化钙10‑20份，硅灰5‑10份，三乙醇胺2‑4份，乙二醇5‑10份，膨胀剂8‑15份。本申请的一种提高混凝土强度和耐久性的早强剂，减少氯化物和硫酸盐对混凝土钢筋的腐蚀和损害，纳米二氧化硅、硅灰和溴化钙相互结合，协同提高混凝土的强度和耐久性，同时减少氯离子的侵入和腐蚀，提高混凝土的抗渗性。
